This is due to AJAX field query endpoints accepting user-supplied filter parameters that override field-configured restrictions without proper authorization checks. This makes it possible for unauthenticated attackers with access to a frontend ACF form to enumerate and disclose information about draft/private posts, restricted post types, and other data that should be restricted by field configuration.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/advanced-custom-fields/tags/6.7.0/includes/fields/class-acf-field-page_link.php#L144","https://plugins.trac.wordpress.org/browser/advanced-custom-fields/tags/6.7.0/includes/fields/class-acf-field-post_object.php#L155","https://plugins.trac.wordpress.org/browser/advanced-custom-fields/tags/6.7.0/includes/fields/class-acf-field-post_object.php#L92","https://plugins.trac.wordpress.org/browser/advanced-custom-fields/tags/6.7.0/includes/fields/class-acf-field-relationship.php#L118","https://plugins.trac.wordpress.org/browser/advanced-custom-fields/tags/6.7.0/includes/fields/class-acf-field-relationship.php#L171"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-4812","score":0.0091,"percentile":0.59979,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
